MIUI 10 doesn't let service start activity - Xiaomi Redmi Note

问题

My app has a service and an activity. From the service, activity is called with following code:

Intent intent = new Intent(getApplicationContext(), MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

even without the flags, normally the activity window is displayed with its correct layout. However, on Xiaomi Redmi Note 4 with Android 7, activity layout is not displayed. I only see the following line on logcat:

I/Timeline: Timeline: Activity_launch_request time:281438674 intent:Intent { flg=0x30000000 cmp=com.test.app/.MainActivity }

I believe this is not an Android 7 (API 24) issue because on another device with Android 7, service can successfully start the activity. I guess, MIUI is preventing the launch of the activity from service.

I tried changing how the activity was defined in the manifest. I also tried with several different flags. All of my tests failed. I could not succeed in starting the activity. Worst issue is that there is no error/exception in the logs.

Any ideas on this please ?

In App Info screen from the system Settings app > Other permissions > Display pop-up windows while running in the background.

This seems introduced in MIUI 11.

Edit: here is a piece of code that I use. I add that into a permission list in a RecyclerView.

Class<?> c = Class.forName("android.os.SystemProperties");
Method get = c.getMethod("get", String.class);
String miui = (String) get.invoke(c, "ro.miui.ui.version.code");
if (!miui.isEmpty() && Build.VERSION.SDK_INT >= 28) {
            PermissionData mPopup = new PermissionData();
            mPopup.text = "Other permissions > Display pop-up while in background";
            mPopup.onClickListener = new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
                    Uri uri = Uri.fromParts("package", getPackageName(), null);
                    intent.setData(uri);
                    startActivity(intent);
                }
            };

            mPermissionData.add(mPopup);
}
